I LOVE LOVE LOVE this product. I'm 34, with fair, oily, somewhat sensitive skin. I am just beginning to be conscious of those lines around the eyes and a general decline in my skin's appearance. I'm a skeptic and when I saw this product I thought, "Copper? What's that for? Is it going to give me a patina so it looks like I'm SUPPOSED to look old?" Well, I've been using it for a little over two weeks now and WOW! The lines around my eyes are gone. I mean gone. My saggy eyelids aren't as saggy anymore, and overall my face feels...firmer. Several friends have commented upon how good my skin looks. This cream absorbs quickly with no oily residue, and I've experienced not a bit of irritation or breakouts. (Since it works so well on oily skin I wonder how it works on dry skin?) Bottom line: It works. Its inexpensive. Its gentle on senstive skin. What more could you want?
